MACHINE FOR ROLLING WHEELS.

SPECIFICATION forming part of Letters Patent 757,432, dated April 19,1904.

' Application filed November 3, 1902- .l'o all whom it may concern:

Be it known that I, FRANKLIN P. -BATES, of Indianapolis, county ofMarion, and State of Indiana, have invented a certain new and usefulMachine for Rolling Wheels; and I do hereby declare that the followingis a full, clear, and exact description thereof, reference being had tothe accompanying drawings, in which like figures refer to like parts.

The object of this invention is to form the surface of bodies-such aswheels, sheave-pulleys, and the likemade of wrought or forged steel oriron. It has been customary to make wheels, sheave-pulleys, and the likeby casting them, the result being a comparatively heavy article withoutgreat wearing qualities. With this invention wheels capable of doing thesame work can be produced more cheaply and are much lighter and arevastly more durable.

In carrying out this invention the metal body when treated is firstdrop-forged, so as i to form the sides and hub thereof, the rim beingleft in an oval or in an unfinished form. The metal body thus formed isheated to a suitable degree and placed between a pair of rotaryclamping-heads which preferably fit snugly against the sides and hub ofthe heated metal body. The rollers are pressed against the periphery ofthe metal body as it is rotated to form the peripheral surface thereofas desired. In this way a wheel can be formed with a regularly-formedtread or peripheral recess with regular and uniform flanges on each sidethereof, so that the wheel will be in a finished form when taken out ofthe machine.

The nature of my invention will be more fully understood from theaccompanying drawings of one form of machine for carrying out myinvention and the following description and claims.

In the drawings, Figure 1 is a perspective of such a machine. Fig. 2 isa central vertical longitudinal section through the machine asshown inFig. 1. Fig. 3 is an enlarged detail of the screws orv means for forcingthe rollers up against the metal body as it is being formed. Fig. 4 is acentral vertical trans- Verse section of the machine. Fig. 5 is a hori-Serial No. 129,921. (No model.)

treated and the parts acting and holding such metal body at thebeginning of the operation. Fig. 6 is the same at the end of theoperation. Fig. 7 is a section on the line 7 7 of Fig. 4.

In detail a general main frame 10 is provided, mounted on suitable legs11 and having longitudinally and horizontally "disposed in its upperpart the bearings 12 for the shafts 13 and 14. There is an opening orworking place in the middle of the frame between the extensions 15 ofthe frame, which are strengthened by the bolt 16. The shaft 13 ismounted in one end of the machine and the shaft 14in the other end, andthe inner ends of both extend into the working space referred to. Theshaft 14 is rotatable, but has no longitudinal movement or play. Theshaft 13 is rotatable and longitudinally movable for adjustment,

as will be explained. The inner ends of both shafts 13 and 14 arethreaded, but reversely;

and each carry a clamping-head formed, preferably, of the part 17,secured on the shafts,

and a die 18. The outer end of the shaft 13 of the shaft 13 isadjustable with relationto the clamping-head on the shaft 14, and bythis means the metal body or wheel being treated is clamped in placebetween the two clamp-- ing-heads. While I show one form of means formoving and clamping the head on the shaft 13, I do not wish to belimited to such means.

The adjacent faces of the dies 18, forming a part of the clamping-heads,are made, preferably, to conform to the surface of the sides of thewheel or metal body to be treated, so as to hold it rigidly whenclamped, and said clamping-heads, with the metal body clamped between,are. rotated by the gear 22, that is splined on the shaft 13. Said gear22 is driven by the pinion 23 on the shaft 24, mounted in the lower partof the frame 10, as shown in Fig. 2. The shaft 24 is the main drivingshaft of the machine, it being driven by the two triangular plates 20and the base-plates 27 and the tie-rods 28, 29, and 30. The purpose ofthis is not only to furnish mounting for the shaft 19, but also for theshafts 13 and 14, to abut against for the purpose of receivingandresisting the lateral strainon said shafts 13 and 14 when the metalwheel or other body is clamped between the clamping-heads. This yoketherefore cooperates with the shoulder s in the bearings-12, whichresist the lateral strain of the clamping-heads 17. The yoke alsorendersthe shafts 13 and 14 rotatable with less friction.

Under the working space in the center of the machine there is atransverse horizontal guideway33,'to be seen in cross-section in Figs; 2and 7, which contains the blocks 34, that carry the rollers for formingthe surface ofthe metal body to be treated. The blocks 34 are eachintegral with an upwardly-extending post 35. Said posts are vcentrallyslotted ,at'their upper ends at 36, in which slots the rollers 37 and 38are mounted by horizontally-disposed arbors 39. There is one of theserollers 37 and 38 on each side of a center line running through the twoshafts 13 and 14, that appears in Figs. 1 and 4.

The blocks 34 are centrally bored to receive a shaft '40, which extendsentirely through both blocks and is held from any'longitudi Figs. 3 and4, that engages thenuts 45, which fit in an enlarged opening within theblocks 34 and are adjustably secured to said blocks by set-screws 46.The'shaft 40 is driven by gear 47, secured on one end, that meshes with;the pinion 48, that is mounted on the shaft 49,

carried in the frame, as shown in Fig. .4, and

having on its inner end a bevel-gear 50, that is driven by abevel-pinion 51,.mounted on the shaft 24. A clutch mechanism 52 throwssaid bevel-pinion 51 in and out of gear with the bevel-gear '50. Theshaft 40 has a;

' hand-wheel 53 secured on the end opposite. the.

gear 47.

The roller 38 slightly oval, as shown in Figs. 5 and 6, while the roller37 is shown with a flat periphery.

The purpose of this difference is to use the roller 38 in advance on themetal body to be treated, as'the oval form of the roller morereadilyfdisplaces the metal in the periphery of the metal body beingtreated, and the roller said rollers.

1 rail.

is made with aperiphery;

37, with the flat periphery, subsequently comes into engagement with theperiphery'of the metal body being treated and gives to it its finalform. To accomplish this mode of operation, the wheel 38 is set incloser to the center of the machine by the set-screw 46 at the left-handend, as shown in Fig. 4, than the roller 37. This causes the roller 38toengage the metal body first. In order to cause the roller 37 to finishthe work, it must move inwardly more rapidly than the roller 38, and tobring about this result the threads on the shaft 40, which ultimatelycause the inward movement of the roller 37 are made coarser than at theopposite end of the shaft 40. While the rollers 37 and 38 are hereinshown to give a certain form to the metal wheel that is, a recessedtread portion witha flange on each sideI do not wish to limit myself toany. particular form of said rollers 37 and 38 or to any particular sortof work they are capable of accomplishing.

The general. operation of the machine will now be explained. The metalbody to be treated, such as the wheel 54, after havingbeen drop-forgedto form the sides thereof and heated, is securedbetween theclamping-heads on the inner ends of the shafts 13 and.14 and securelyclamped thereinby the hand-wheel 21. The metal body or wheel 54 willthen be rotated through the driving mechanism' above describedv fordriving the shafts 13 and 14. The bevel-pinion 51 is thrown into gearwiththe gear 50, which causes the shaft 40 to rotate, and 7 thatgradually moves the rollers 37 and 38 up to the wheel and presses saidrollers into the; periphery thereof in the order preferably that hasheretofore been described for the action of The effect of said rollersis to centrally displace the metal in. the periphery of the. wheel beingformed, so. as toma'ke an anform regular and uniform flanges on saidwheel that extend .beyond the tread portion thereof to hold on apulley-rope or otherdriving =means or to guide the wheel in any use towhich it may be put, such as running on :a. When the wheel is thuscompleted, the

bevel-pinion 51 is thrown out of gear withthe bevel-gear 50 and thatstops the inwardmove- :ment of the rollers 37 and 38. :By reversing theshaft 40, through the instrumentality of the hand-wheel 53, the rollers37 and .38, are

separated and disengaged from thewheel be- 5 ing formed, andthe'clampingshead .is released by the reversing of the hand-wheel 21,whereupon the wheel being formed can be removed and will be in itscompleted form;

The mechanism shown herein to illustrate the general nature of myinvention is to some extent a specific form,.and as it is arrangedltomake a certain style of metal wheel Iwish toexplain further some of theparts in connection with Figs. 5 and 6. Those figures show the positionof the clamping-heads and rollbeing treated, so as toclamp the same atthe hub and web portions tightly. They do not clamp the rim portiontightly, but, in fact, leave ample space for the spreading of the metalin the rim, as shown. At that point the dies should be formed to givethe desired shape to the sides of the rim. i

As shown herein, the die has an outwardlyslanting portion and aninwardly-slanting portion 61, so as to curve therim as desired. The diesalso have a straight face at 62 for the purpose of furnishing a guidewayfor the rollers 37 and 38, the idea being that said rollers shall fitrather snugly between the dies and operate between the straight faces 62thereof.

This prevents the escape of metal and also guides the rollers. In whatis shown herein one of the rollers 38 is somewhat oval in crosssectionto effect the initial displacement of the metal in the wheel beingformed, while the other wheel is plain and flat togive the final form.

It is obvious if the tread portion of the wheel is desired to bedifferent the rollers should be correspondingly changed in form. Whilethe wheel herein shown is a lumber-truck wheel adapted to run on arailway, the wheel might be made with a different rim and for differentpurposes.

What I claim as my invention, and desire to secure by Letters Patent, is
